“What salary can I expect in industry after my PhD?”
For many young researchers, the PhD graduation marks the end of an era of standardized salaries. They now have to negotiate their salary when entering the industry or moving to a non-university research organization. Below are some tips on how to approach these negotiations. An Austrian-German perspective.
UWB sensor networks in airplanes
The airplane industry is interested in replacing heavy cables in aircraft by wireless connectivity. We are currently investigating the potential and feasibility of ultra-wideband (UWB) technology as an option for such systems.

Synchronization with phase rate correction
Synchronization algorithms based on the theory of pulse-coupled oscillators are evaluated on programmable radios. It is experimentally demonstrated that the stochastic nature of coupling is a key ingredient for convergence to synchrony. We propose a distributed algorithm for automatic phase rate equalization and show that synchronization precisions below one microsecond are possible. Read More
